Abstract

A container, having a plurality of microspheres, the microspheres containing substances, which when liberated from the microspheres, result in an endothermic or exothermic reaction or change of state resulting in a temperature change to the proximate container and contents contained therein, for bringing the contents to a substantially cooled or heated condition with respect to starting temperature.

Claims

exact text as granted — not AI-modified
I claim: 
     
       1. A building material, having a plurality of microspheres, said microspheres containing substances, which when liberated from said microspheres, result in an endothermic or exothermic reaction resulting in a temperature change to (the) a proximate container and of (the) contents contained therein, for bringing the contents to a substantially cooled or heated condition with respect to a starting temperature. 
     
     
       2. The (container) building material of claim 1 wherein said (substances) building material (include) includes a gas or chemical such as water, a base or an acid. 
     
     
       3. The (container) building material of claim 1 wherein microscopic slivers of steel or fiberglass, natural or synthetic fibers, are used to aid in distruction and fracture of the microspheres. 
     
     
       4. The (container) building material of claim 1 wherein said slivers are steel, glass, plastic, or synthetic or natural fibers. 
     
     
       5. The (container) building material of claim 1 wherein the building material is (substances are) encased within a sealed membrane, bladder or strip comprising microspheres. 
     
     
       6. The (container) building material of claim 5 wherein said strip is plastic or paper; comprised of microspheres containing the building material. 
     
     
       7. The (container) building material of claim 5 wherein said membrane comprising the building material is silicone rubber, plastic, polymer or monomer. 
     
     
       8. The (container) building material of claim 5 wherein said mambrane, bladder or strip comprising the building material is attached to the outside or inside of (said) a container or installed within (said) a container, or comprises the container. 
     
     
       9. The (container) building material of claim 1 wherein said substances contained in the microspheres comprising the building material cause a temperature change of at least 15 degrees Fahrenheit (in) to the contents of (the) a container. 
     
     
       10. The (container) building material of claim 1 wherein said (substances) building materials comprise microcapsules containing ammonium nitrate or magnesium sulfate. 
     
     
       11. The (container) building material of claim 1 wherein said reaction (or change of state) is endothermic whereby cooling is accomplished. 
     
     
       12. The (container) building material of claim 1 wherein said reaction (or change of state) is exothermic whereby heating is accomplished. 
     
     
       13. The (container) building material of claim 1 wherein said (container) building material comprises (is) a container. 
     
     
       14. The (container) building material of claim 1 wherein said (container) building material (is) comprises a metal, plastic of glass. 
     
     
       15. The (container) building material of claim 1 wherein the microspheres (are provided within) comprise a wall of (the) a container (itself,) or (within) comprise the entirety of the container. 
     
     
       16. The (container) building material of claim 1 wherein two sets of microspheres, in combination with polymeric substance, comprise, substantially, (the) a building material. 
     
     
       17. The (container) building material of claim 1 wherein the microspheres (are provided by) comprise a stirrer; an object containing like microspheres. 
     
     
       18. The (container) building material of claim 1 wherein the microspheres possess a wall thickness of between 0.25 and 100 micrometers. 
     
     
       19. A (stirrer) building material (having) comprising a plurality of microspheres, said microspheres containing substances, which when liberated from said microspheres, result in an endothermic or exothermic reaction (or change of state) resulting in a temperature change, whereby the contents of a container may be brought to a substantially cooled or heated condition with respect to starting temperature. 
     
     
       20. A (stirrer) building material comprised of polymer and microspheres, which form a composite capable of producing endothermic and exothermic reactions or changes (of state) in temperature. 
     
     
       21. The (stirrer) building material of claim 20, capable of changing color through incorporation of dye. 
     
     
       22. The (stirrer) building material of claim 21 wherein the dye is approved for human consumption. 
     
     
       23. The (stirrer) building material of claim 22, wherein the microsphere is constructed of (stuff) material approved for human consumption, such as Phenol Blue or #2 Yellow Dye. 
     
     
       24. (A) The building material of claim 1, comprising matrix and microspheres containing chemicals.
